Title: Improvements in or relating to method and apparatus for the estimation of surface areas of solids
Inventor: NELSEN FRED M
IPC: G01N15/08
Filed: 1958-04-30
Abstract: 831,639. Surface area estimating apparatus. BATAAFSCHE PETROLEUM MAATSCHAPPIJ N.V., DE. April 30, 1958, No. 13761/58. Drawings to Specification. Class 40 (1). A method of estimating the surface area of a solid material comprises passing a stream of a gaseous mixture of an adsorbate and an inert diluent gas over a known quantity of the material at a temperature such that the adsorbate is not adsorbed, then lowering the temperature of the material so that the adsorbate is selectively adsorbed and measuring the amount of gas adsorbed at the lower temperature. The apparatus comprises means for supplying known constant streams of both gases to the sample, means for sensing and recording the concentrations of the gases, and means for adjusting and maintaining the sample at two widely spaced temperatures. Preferably the concentrations of the gases are measured by thermal conductivity cells in the gas streams before and after the sample, the two cells being arranged in a bridge circuit whose output is fed to a recording self-balancing potentiometer. When the sample is cooled or heated the change in composition of the gas flowing through the second cell unbalances the bridge circuit which unbalance is recorded by the potentiometer over a period of time as a peak on the recorder trace. The area under the peak, measured by a planimeter, is a measure of the gas adsorbed or desorbed by the sample under test, and therefore of the surface area of the sample.

Filed: 1972-03-24
Abstract: 1334632 Shutter control EASTMAN KODAK CO 24 March 1972 [24 March 1971] 13832/72 Heading G2A A camera having an RC circuit for determining the interval between the movement of a first blade 1 to uncover an exposure aperture 5 and a second blade 2 to cover the aperture, includes an over-ride arrangement for preventing movement of blade 2 to the covering position and for permitting blade 1 to return immediately to the covering position to provide a mechanically determined shutter speed effected by blade 1 alone. Over-riding is effected by inserting a flash-lamp (43), Fig. 4 (not shown) or by manually operating a lever 50. As shown, for RC control, when a lever 18 is depressed a driver 12 is allowed to open blade 1 and to release a control lever 21 which moves to free blade 2 and a latch 26. Latch 26 rotates to lock blade 1 in the open position. When an electromagnet 29 is deenergized by the RC circuit 79, 80, a latch 30 is released and a spring 9 closes blade 2. When a flash-lamp is inserted, a lever 50 is manually operated, a lever 40 is depressed to lock control lever 21 in position. Therefore when release 18 is depressed blade 1 is moved to the open position by driver 12 and then is returned to the closed position by a spring 6; the blade 2 and latch 26 being held by control lever 21. A lamp 74 is illuminated before exposure if the light is insufficient, and is illuminated during exposure to indicate its duration. A battery test lamp 67 is provided.

Title: Improvements in or relating to telegraph signal regenerators
IPC: H04L25/04
Filed: 1939-05-09
Abstract: 531,820. Telegraphy. CREED & CO., Ltd., MASON, F. P., and MITCHELL, W. A. May 9, 1939, No. 13851. [Class 40 (iii)] [Also in Group XXXV] A signal generator or regenerator comprises an electromagnetic or other rotary generator of short impulses operated in timed relation with the signals to be generated or regenerated, and means whereby each impulse may cause either a marking or a spacing condition to be set up. The generator may comprise a notched wheel 20 moving an armature 26 in the field of a magnet so as to produce impulses in a coil 29, or a disc D shaped as in Fig. 3 and rotated in the field of an electromagnet. Regenerator for a start-stop equal-length code, Fig. 1. The notched disc 20 has seven notches for generating starting, stopping, and five code impulses, and is released by magnet 9 on the receipt of a start signal. The gas-filled valves 3, 5, 6 are biased from batteries 31, 32, but when a marking current is on the line L1 the positive potential of battery 30 is applied over 29, 36, 10 to the grid of valve 3, which conducts and applies marking current to line L2. When spacing current is received, armature 36 moves to contact 4 and battery 30 is applied to the grid of valve 5, which causes magnet 9 to release the generator, and change over contacts 23, 24, 37, thereby extinguishing valve 5. When the first notch ST engages the follower 25, the impulse produced in coil 29, superposed on the potential of battery 30, is applied to the grid of valve 6, which de-energizes valve 3 and sends a start signal to line L2. At the middle of each subsequent signal period, the impulse in coil 29 is applied, together with battery 30, to the grid of either valve 6 or valve 3, according to the position of armature 26, thus regenerating the signals in line L2. Generator for start-stop transmitter. The contacts A1 ... A5 of a keyboard or tape transmitter are connected to the distributer 44 and the impulse coil 40 of the generator is connected by a rectifier 41 to the junction of the two windings 42, 43 of a transmitting relay. If an impulse is generated in coil 40 at a moment when the distributer brush is connected to an open contact A1 ... A5, current flows through winding 43 only and a spacing current is transmitted. If the distributer brush is connected to a closed contact A1 ... A5, current flows through both windings of the relay, and, owing to the resistance 47, winding 42 predominates and transmits a marking current. The distributer and contacts A1 ... A5 may be replaced by a single contact closed selectively by cams.

Abstract: 1,036,967. Selective printing. DATA PRODUCTS CORPORATION. April 6, 1964 [June 17, 1963], No. 14027/64. Heading B6F. Type-wheel machines; hammer impression arrangements.-A hammer assembly for a selective printer having a type carrier 10, Fig. 1, having a plurality of small and large impression area characters thereon is characterized by means for determining whether a character towards which a hammer 16 is to be impelled is a small or large impression area character and for urging the hammer with a first force towards a small impression area character and with a second force towards a large impression area character. Each hammer 16 is supported on spaced conductive, resilient and flexible support members 18 and 20, which also serve as terminals for a coil 22, received between a pair of spaced permanent magnets 24 and 26. Physically opposed poles on the magnets 24 and 26 are of opposite magnetic polarities so that when a current is initiated in the coil 22 in one direction the hammer will be propelled for impression. By reducing the amplitude of current when the hammers are to strike a small impression area character a reduced energy will be imparted to the hammers and vice versa. The hammers are restored by the resilient supports 18 and 20, rebound being prevented by maintaining the current in the coils 22 subsequent to the hammers striking the type carrier 10 so that the restored hammers strike the backstops 28 with a diminished energy. The backstops are adjustable to facilitate the control of intensity of impression. Types, discs and printing surfaces.-The small impression area characters, e.g. full stops and commas, which are printed at the bottom of a line are positioned in such a manner that they occupy the top of a character position on the drum 10, Fig. 1.

Title: Device for the gasification of finely divided fuels
IPC: C10J3/46
Filed: 1959-04-24
Abstract: 911,374. Gasifying fuels. KOPPERS G.m.b.H., HEINRICH. April 24, 1959 [April 30, 1958], No. 14096/59. Classes 55 (1) and 55 (2). In a device for the gasification at elevated temperatures of finely divided fuels in suspension with a gas which is oxygen or oxygen-enriched air, or a blend thereof with endothermically-reacting gasifying agents (such as steam and/or carbon dioxide), the mixture of the finely divided fuel and said gas is blown through a nozzle into a reaction chamber, which widens conically in the direction of flow of the mixture and which opens into a gas-collecting chamber, from which the gas produced is discharged upwardly and any gasification residues are discharged downwardly, the reaction chamber being rigidly fixed and the inlet pipes for fuel and gas being rigidly connected thereto, the gascollecting chamber however being connected to the reaction chamber in a gas-tight but non- rigid manner. In this way, the gas-collecting chamber can move relatively to the reaction chamber, under the action of thermal expansion. The fuel to be gasified may be a solid fuel in powder form, or a liquid fuel (e.g. hydrocarbon oil) in vaporous or atomized form. In the drawing, finely divided solid fuel is fed towards the reaction chamber 4 by means of worm 9 and is blown into the reaction chamber by oxygen admitted through hollow shaft 10. The endothermically-reacting gasifying agent is introduced into the reaction chamber through annular duct 12. The reaction chamber 4, which widens conically towards the gas-collecting chamber 2, has walls of refractory masonry 3 and is surrounded by a cooling water system 5. A high temperature is maintained in the reaction chamber so that the fuel ignites immediately upon entry therein. If desired, a plurality of reaction chambers, rigidly connected together, may lead to a single gas-collecting chamber. The gas-collecting chamber 2 also has walls of refractory masonry 6 and is surrounded by a cooling water system 7. Reaction chamber 4 is supported on a stand 13 and is also rigidly connected to pipes supplying the reaction media. Packing 14 permits relative movement between the reaction chamber, whilst at the same time preventing escape of gas.
